Today, hp_jack_event and mic_jack_event always return 0. However, snd_soc_dapm_disable_pin and snd_soc_dapm_enable_pin may return a non-zero value, this will cause the user who calling hp_jack_event and mic_jack_event don't know whether the operation was really successfully. This patch corrects the behavior by properly returning 1 when the value gets updated.
